Strength Evaluation

Strength evaluation and failure prediction on a modern composite wind turbine blade have been conducted using finite element analysis. A 3-dimensional finite element model has been developed. Stresses and deflections in the blade under extreme storm conditions have been investigated for different materials. The conventional wood design turbine blade has been compared with the advanced E-glass fiber and Carbon epoxy composite blades. Strength has been analyzed and compared for blades with different laminated layer stacking sequences and fiber orientations for a composite material. Safety design and failure prediction have been conducted based on the different failure criteria. The simulation error estimation has been evaluated. Simulation results have shown that finite element analysis is crucial for designing and optimizing composite wind turbine blades.

Horizontal Axis Wind Turbine

Abstract: Nowadays wind turbine is used widely in many countries as power plant. When the wind turbine blade rotates there will be aerodynamic forces acting on the blade such as drag, lift, weight and centrifugal forces. When designing wind turbine blade it is necessary to test whether the blade can withstand the aerodynamic forces or not. Stress analysis is a feature that can predict stress acting on construction. Nowadays there are many stress analysis softwares that can be used to predict stress. In this research the stress analysis will be used by using autodesk inventor.The research purposes are to find the stress acting on the wind turbine blade and to get the maximum stress location.

Abstract: Base on finite element method of composite, take 5MW horizontal axis wind turbine blades as example, skin uses a mixture of fiberglass and carbon fiber as ply, spar caps and web adopt carbon fiber ply entirely to build the finite element model of the blade. The total weigh of the blade is 20.2 ton. Use Bladed software calculated the limit load of each cross-section, analyzed the stress distribution of each section and the modal characteristics of the blade, these provide a theoretical reference for the application of carbon fiber using on MW class wind turbine blade.
